The question of what Donald Trump calls himself is one that I have never asked myself, but on Thursday, the answer was revealed. In former FBI deputy director Andrew McCabe’s upcoming book The Threat: How the FBI Protects America in the Age of Terror and Trump, he shares this pleasant phone call he received one day from the president:

The Russia team was in my office. I took the call on an unclassified line. That was another strange thing—the president was calling on a phone that was not secure. The voice on the other end said, It’s Don Trump calling. I said, Hello, Mr. President, how are you? Apart from my surprise that he was calling at all, I was surprised that he referred to himself as “Don.”

Don went on to say:

Toward the end of the conversation, the president brought up the subject of my wife. Jill had run unsuccessfully for the Virginia state Senate back in 2015, and the president had said false and malicious things about her during his campaign in order to tarnish the FBI. He said, How is your wife? I said, She’s fine. He said, When she lost her election, that must have been very tough to lose. How did she handle losing? Is it tough to lose?

I replied, I guess it’s tough to lose anything. But she’s rededicated herself to her career and her job and taking care of kids in the emergency room. That’s what she does.

He replied in a tone that sounded like a sneer. He said, “Yeah, that must’ve been really tough. To lose. To be a loser.”
